Description

For T89630, some indexes were reordered to make queries more efficient. But the index changes do not seem to have actually been deployed everywhere, for example the old index ordering is still present on db1070 dewiki.pagelinks and db1089 enwiki.pagelinks.

See https://gerrit.wikimedia.org/r/#/c/190774/ for the specific changes involved.

This affects almost all servers, all wikis; it will be easier to apply the change to all wikis rather than selectively.

So this change has been deployed to all hosts, but when I was finishing it, I realized I missed the imagelinks reorder. No time has been wasted, but I have to recreate that table, too on all servers. It should be faster than the other ones, I think.

However, it may take another month to be fully deployed so this can be closed. :-(

After running over 30 000 alter tables, this is nominatively done; however, it is highly likely that some failed and could not be retried; for example if they were under maintenance at the time, network errors, human mistakes, etc.

We need to check all tables and rerun the alters where missing, to make sure everything is consistent.

I will not fix labsdb1001 and labsdb1003- they are at EOL, and the new ones will have the right structure; plus it will create unnecessary lag and metadata locking to users.

This makes those tables missing (aside from the 2 down hosts):

Now that dbstore2002 is up again, I can see it is fully ALTER'ed for the shards that it contains (s1, s4, s3).
db2034 is considered broken, so no issue with that.

I will depool db1080 and db1089, sequentially, to apply the latest 2 schema changes (probably they failed because high concurrency).
